5, streams and lakes throughout Southeast Alaska and Prince William Sound. In approximately a dozen “trophy” lakes in Southeast Alaska, CCT may grow to be over 25 inches and exceed 15 years of age.

Coastal cutthroat trout occur as sea-run or freshwater-resident forms in streams and lakes along the coastal range from lower Southeast Alaska to Prince William Sound and are the most common trout species in the region.

The freshwater-resident form lives in a wide variety of habitats, from small headwater tributaries and bog ponds to large. Southeast Alaska that receive significant fishing effort for cutthroat trout, and therefore includes documented occurrence of the species in lakes across Southeast Alaska.

Coastal cutthroat trout (Oncorhynchus clarki clarki, “CCT”) are distributed along the Pacific coast from Prince William Sound, Alaska, to the Eel River, California (Figure 1). They exhibit complex life history forms and migration patterns, ranging from non-migratory, freshwater-migratory, and saltwater-migratory.

Coastal cutthroat trout have a highly variable life history ranging from fully anadromous to resident. they are the most freshwater-dependent of the anadromous salmonids, migrating to the ocean for only a few months in the summer.

they are competitively subordinate to nearly all other salmonids. Coastal cutthroat trout in spawning coloration. Photo: Alaska Department of Fish and Game Abundance, distribution, and natural history.
